Before, during and after a mega storm, the next item people worry about after shelter, food and water for themselves, friends and relatives, is up-to-date weather and transportation information.

Sandy brought more than rain and flooding. The hurricane turned tropical storm also resulted in snow as it interacted with other weather systems. Knowing about road conditions becomes even more important when heading into winter.

Here are some sites that have reliable statistics and other data:

For weather: AccuWeather has up-todate information with additional weather warnings from Justin Roberti at State College, PA.

Among his latest information is that the 1977 Hurricane Gladys was the strongest hurricane north of Cape Hatteras at a low barometric pressure of 27.73 inches. Sandy’s low barometric pressure was offshore Monday at 27.76 inches.

Also on the site are rain and snow totals and surges. According to the AccuWeather site the highest surges were at The Battery, NY at 9 feet above normal, Kings Point, NY at 12.5 feet above normal and New Haven, CT at 9 feet above normal.

For air traffic and cancellations: Go to Flight Aware. For Sandy the site showed more than 8,000 cancellations Monday and more than 6,000 Tuesday by airline, airport and destination. The site also has flight tracker information.

Along with checking your flight departure, learn what is happening at destination or transfer airports.

Rail transportation: See Amtrak for general information and visit alerts for disruptions.

Road: Each state has a department of transportation that tells road conditions. I highly recommend checking these state sites before starting out on a road trip. In Illinois it is IDOT. However, the federal government also has a DOT Web site . Visit resources for services and alerts.
